Re: USMC Knife Doctrine
In MCMAP, as you go up from tan, grey, green, brown, then black belt the knife/bayonet techniques get more and more "complex." Tan belt is very very basic slashes, perry's, and thrusts. I don't really remember what they taught in grey, I think it was mostly bayonet. Green was a little more in depth, some counters to both armed and unarmed attackers. Brown belt was a lot more in depth as far as counters to armed and unarmed attackers. Also did a lot of disarming techniques for both knife and firearm wielding attackers. I'm not a black belt, so I can't speak for that.
